You didn't attach a complete log so it's hard to tell. ath10k tends to
print a few messages that may look like an error but aren't (there's a
fallback mechanism for finding firmware files which is overly
verbose).

@Perry: You need to rename the
firmware-4.bin_WLAN.RM.2.0-00180-QCARMSWPZ-1 to firmware-4.bin in case
you merely mirrored the github repo.

@Kalle: I think it'd be very useful to maintain ath10k-firmware in a
way so that it is easier to the uninitiated to `git clone` it into
/lib/firmware, e.g. maintain firmware-X.bin symlinks in each
QCAxxx/hw.y/ to the latest one. Thoughts?
